Spring框架

Spring是一个开源框架，Spring是于2003年兴起的一个轻量级的Java开发框架，由RodJohnson创建。

简单来说，Spring是一个分层的JavaSE/EEfull-stack（一站式）轻量级开源框架。

强大的基于JavaBeans的采用控制反转（InversionofControl，IoC）原则的配置管理，使得应用程序的组件更加快捷简易。

1.方便解耦，简化开发

通过Spring提供的IoC容器，我们可以将对象之间的依赖关系交由Spring进行控制，避免硬编码所造成的过度程序耦合。

有了Spring，用户不必再为单实例模式类、属性文件解析等这些很底层的需求编写代码，可以更专注于上层的应用。

2.AOP编程的支持

通过Spring提供的AOP功能，方便进行面向切面的编程，许多不容易用传统OOP

实现的功能可以通过AOP轻松应付。

3.声明式事务的支持

在Spring中，我们可以从单调烦闷的事务管理代码中解脱出来，通过声明式方式灵活地进行事务的管理，提高开发效率和质量。

4.方便程序的测试

可以用非容器依赖的编程方式进行几乎所有的测试工作，在Spring里，测试不再是昂贵的操作，而是随手可做的事情。

例如：

Spring对Junit4支持，可以通过注解方便的测试Spring程序。

5.方便集成各种优秀框架

Spring不排斥各种优秀的开源框架，相反，Spring可以降低各种框架的使用难度，

Spring提供了对各种优秀框架（如Struts,Hibernate、Hessian、Quartz）等的直接支持。

6.降低JavaEEAPI的使用难度

Spring对很多难
